About The Position

The Senior Structural & Multibody Dynamics Simulation Engineer on Caterpillar’s Industrial Power Systems Division structural and multi-body dynamics team leads and executes core rotating component simulations using tools such as RUMBLE/BEAR, Abaqus, AVL EXCITE, or other multibody dynamics tools. The engineer applies technical expertise to identify, analyze, and help resolve complex problems involving crankshafts, camshafts, connecting rods, bearings, and related engine systems, and communicates risks, results, and recommendations to stakeholders. The role focuses on technical delivery, project leadership, and communication. The engineer partners with design, simulation, test, and platform teams to scope, plan, execute, and interpret analyses that improve component performance and durability. The position also contributes to simulation standard work, provides technical guidance and knowledge sharing, supports data-driven technical decisions, and helps improve tools and processes to enhance accuracy, robustness, and turnaround time. The position is onsite five days a week, with travel of less than 10%. Relocation is available; visa sponsorship is not available.

Experience with multibody dynamics tools such as Dynasty/TomSim, RUMBLE/BEAR, AVL EXCITE, Adams, Virtual.Lab Motion, or similar platforms.
Strong understanding of engine dynamics, vibration, bearing performance, and crank train system behavior.
Ability to develop, validate, and correlate simulation models against test measurements and field data.
Ability to lead technical reviews and communicate complex simulation findings to engineering, manufacturing, and program leadership teams.
Experience supporting engine development programs through design reviews, root cause investigations, and resolution of field reliability issues.

Responsibilities

Lead core rotating component simulation activities for crankshafts, camshafts, connecting rods, bearings, and related engine systems across supported platforms and applications.
Partner with component, platform, test, and design teams to clarify analysis needs, prioritize tasks, and deliver timely, high-quality durability and performance assessments.
Use multibody dynamics, finite element analysis, and engine system understanding to troubleshoot complex issues, evaluate design trade-offs, and support root cause analysis for development and field concerns.
Contribute to and improve simulation standard work, including model setup, correlation, result interpretation, quality checks, and documentation of assumptions and recommendations.
Conduct reviews with customers and communicate technical information clearly, translating complex simulation results into risks, options, and actionable recommendations for technical and non-technical stakeholders.
Support multiple priorities and customers by aligning expectations, tracking deliverables, escalating risks, and communicating project status and technical decisions.
Provide technical guidance and knowledge sharing to engineers and external resources through coaching, technical reviews, training, and collaboration.
